maybe your baby is still not yet ready to try other kinds of food. I would suggest you give your baby rice cereal first for a while. if your baby is OK with rice cereal after giving it for 2 or 3 weeks, you can try introducing vegetable. Try one kind of vegetable each time, and each new kind of vegetable must be given for a continuous 4/5 days to see if baby develops any negative reaction to it. If baby develops red dots, has runny pooh pooh or vomit, stop giving that food immediately as she may be allergic to it.
When first introducing solids, the vegetable must be very well blended into容. 你可以試紅蘿蔔(but don't eat too much or else baby will develop very yellow skin), apple, pumpkin. Or you can buy the gerber first stage bottled baby food to let baby have the experience (comes in a pack of 4 small bottles and you can get it from Toys R'us).
